Biofortification, that is, the dietary supply of Se through its enrichment in food and feed crops, is being explored as a possible solution for Se deficiency (Lavu et al., 2013; Li et al., 2010; Thavarajah et al., 2008). This chapter gives insights into factors affecting Se toxicity and deficiency for humans and animals, and meanwhile summarizes the different phytotechnologies used for Se biofortification, including conventional plant breeding and genetic engineering, and soil and foliar application of Se-based fertilizers (agronomic biofortification), with specific attention to the use of Se-enriched organic materials and nano-sized selenium (SeNPs), and the addition of beneficial microorganisms into soil for enhancement of Se accumulation in the crops. The factors influencing Se biofortification strategies are also discussed.
